VOCIA AMPLIFIERS VA-2060, VA-2060e, VA-4030, VA-4030e
The VA-2060, VA-2060e, VA-4030 and VA-4030e are digital networked multi-channel audio amplifiers designed for use in Vocia systems.
All models are CobraNet
®
enabled and feature either two or four channels of amplification, with on-board DSP. Channel-to-channel or
device-to-device failover may be user configured. Each amplifier channel has user selectable support for 4 or 8Ω operation or Constant
Voltage operation of 25, 70 or 100 Volts. The on-board DSP provides comprehensive fixed-chain digital signal processing within the device,
including volume control, ducking, equalization, compressor/limiting, speaker crossover, delay and output gain. Locally stored audio mes-
sages are retained in non-volatile memory within the amplifier. Intuitive software provides audio system design via PC computer. Two RJ45
connectors on the rear panel of the amplifier provide redundant connectivity to control data and audio over a single Ethernet cable. The
VA-2060e and VA-4030e models have the ability to be powered via dual 24V connections in addition to the AC mains power supply, as well
as balanced mic/line inputs to be used as a local background input source for the output channel associated with the Input.
SET UP AND USE
The Vocia software provides the interface for configuring and programming the VA-4030(e) and VA-2060(e) amplifiers. The information
supplied by this manual relates to hardware installation, physical connections and device and channel failover concerns. For more details
on software setup, please consult the Vocia Software Help File.
